This massive shift in Colombian history can be traced to one single day: April the 9th, 1948. It was on this day, shortly after the failed liberal campaign for presidency, that liberal leader Jorge Eliecer Gaitán was assassinated. This triggered mass civilian rioting in the streets of Bogotá, which came to be known as the Bogotazo. Shortly thereafter, government counterrevolutionary forces arrived and began massacres of the rioting population, performing such acts as impaling infants on pikes. These traumatic events led to the 10-year La Violencia, in which intense conflict between Liberals and Conservatives left 300,000 dead.
